GGM K8G Gearhead – 80mm Parallel Shaft Gearbox for 25W GGM Motors

GGM K8G Gearhead – 80mm Parallel Shaft Gearbox for 25W GGM Motors

The GGM K8G Gearhead is a parallel shaft gearbox series from GGM, specifically designed for 25W GGM motors with an 80mm flange size. This product is used to reduce output speed, increase transmission torque, and ensure stable operation of motor assemblies in compact automated machinery.

The K8G gearhead is compatible with 25W GGM motors, featuring K8G...B(C) models and an optional K8G10BX decimal gearhead for higher reduction ratios. This series is ideal for drive assemblies requiring a compact footprint, direct motor mounting, and easy maintenance.

GGM K8G gearheads are commonly applied in mini conveyors, small packaging machines, labeling machines, rotary mechanisms, feeding systems, automated testing equipment, product sorting machines, OEM equipment, and small-capacity drive units. With a wide range of gear ratios, the K8G series allows users to easily select the appropriate output speed for specific operational requirements.

Key Features of GGM K8G Gearhead

The GGM K8G gearhead features a compact, square-box design, perfectly matched to GGM motors with an 80mm flange. The parallel shaft configuration enables direct transmission, making it easy to integrate into space-constrained machinery while maintaining stable performance.

The K8G series offers a variety of gear ratios, from low ratios such as 1/3, 1/5, 1/10 to high ratios like 1/100, 1/150, 1/200, 1/250. Low gear ratios are suitable for applications requiring higher output speeds, while high gear ratios are ideal for mechanisms needing slower speeds and higher torque.

For deeper speed reduction, users can integrate the K8G10BX decimal gearhead, providing an effective solution for applications requiring lower output speeds than standard ratios allow.

The strengths of the GGM K8G gearhead include easy model selection, simple replacement, compact design, and suitability for various small-capacity automation applications. This series is particularly well-suited for systems requiring stable transmission, quiet operation, and optimized installation space.

GGM K8G Gearhead Model List

In addition to these popular ratios, the K8G series offers many intermediate ratios such as 3.6, 6, 7.5, 9, 12.5, 18, 25, 36, 40, 60, 75, 90, providing greater flexibility in selecting output speed and torque for specific applications.

Dimensions and Installation Structure

The GGM K8G gearhead uses an 80mm flange, mounting directly to the 25W GGM motor of the same size. The square-box design facilitates easy machine layout, especially in small drive assemblies where space-saving is critical.

Gearhead weight varies by gear ratio group. Higher ratio groups typically have larger dimensions and weight; therefore, when replacing, ensure the correct old model, installation length, and actual machine space are verified.

GGM Motors Compatible with K8G Gearhead

The K8G gearhead is used with 80mm, 25W GGM motors. Compatible motor series include lead wire types, terminal box types, and T5 terminal box types.

Motor information is only for identifying mounting compatibility. When selecting a product, the focus should remain on the K8G series, gear ratio, B/C type, flange size, and actual installation space.

For 3-phase motors with voltages above 380V, it is not recommended to use them with VFDs as this may affect the motor winding insulation. This is a critical point to consider when selecting motor-gearhead combinations for automation machinery.

Applications of GGM K8G Gearhead

The GGM K8G gearhead is suitable for small-capacity drive mechanisms requiring stable output speed, compact size, and easy replacement.

Common applications include:

• Mini conveyors

• Small packaging machines

• Labeling machines

• Feeding systems

• Product inspection machines

• Product sorting machines

• Slow rotary mechanisms

• Light-load push/pull mechanisms

• Compact automation equipment

• OEM machinery

• Drive units in production lines

With various gear ratios, the K8G gearhead helps users select the appropriate output speed for each machine mechanism. Low gear ratios are suitable for mechanisms requiring faster speeds, while high gear ratios are suitable for mechanisms requiring slow, stable operation and better pulling force.

How to Select the Right GGM K8G Gearhead

When selecting a GGM K8G gearhead, it is essential to identify the correct model and gear ratio to avoid incorrect output speeds or incompatibility with actual loads.

Information to verify includes:

• Whether the motor is the correct 80mm size, 25W capacity

• Whether the gearhead required is K8G...B or K8G...C

• The required gear ratio

• Desired output speed

• Actual load torque

• Installation space on the machine

• Whether the gearhead length is suitable for the mounting position

• Whether an additional K8G10BX decimal gearhead is required

If high output speed is needed, low ratios such as 1/3, 1/5, or 1/10 can be selected. If slow speed and higher pulling force are needed, high ratios such as 1/50, 1/100, 1/150, 1/200, or 1/250 are suitable.

Notes on Replacing GGM K8G Gearhead

When replacing a GGM K8G gearhead, customers should fully verify the information on the old product label. Important information includes the K8G series, gear ratio, B or C designation, flange size, and the model of the attached motor.

It is important to distinguish between models such as K8G10B, K8G20B, K8G50B, K8G100B, K8G200B, as each model has different gear ratios, output speeds, and torque ratings.

Selecting the wrong gearhead can result in improper mounting, incorrect speeds, lack of pulling force, noise, or reduced service life of the drive assembly. For operating machinery, it is recommended to photograph the motor label, gearhead label, and installation position for reference before replacement.
